The Kutentha dongosolo la mipope polypropylene: ubwino ndi mbali ya unsembe

Chibwenzi, lalikulu-kufala dongosolo la Kutentha polypropylene mipope. Ichi ndi chifukwa chakuti masiku ano kuikira mankhwala ndi chiwerengero cha mwayi ndi ubwino omwe analibe akapolo anzawo akale (mipope PVC ndi zovekera anapangidwa kuchokera polyethylene).

ubwino

Industrial mankhwala zopangidwa polypropylene ndi cholimba kwambiri. Ngati inu molondola kusankha mtundu anakhumba, iwo akhoza mzaka 50 kapena kuposa. Polypropylene timachubu, chifukwa njira yapadera kapangidwe ndi kupanga, musati amafuna zina kutchinjiriza kudetsa ndi chisiyeni padziko condensation.

Kutentha ndalama pamene ntchito mankhwala amenewa ndi 20%. Machubu musati dzimbiri, sumangoyambika mkati mwa madipoziti Mbali yokhala ngati ndi zolengeza kupitirira apo mwangwiro yosalala mkati makoma, amene kumatha mikangano ndi kukana, motero madzi umayenda momasuka kudzera chitoliro lapansi. Iwo sali ndi wochititsa magetsi. Kuwonjezera Kutentha kwa machubu polypropylene angathe komabe chizindikiro kutentha mbiri ya 95 ° C.

Zamgululi n'zosavuta kunyamula ndi unsembe, monga opepuka kwambiri kuposa chitsulo. Mosavuta kudula ndi lumo wapadera. Unsembe wa mapaipi polypropylene a dongosolo Kutentha zimatenga nthawi pang'ono. Pakuti kugwirizana ndi chitoliro ndi zovekera amafuna wapadera soldering chida. Pankhaniyi, malekezero a mankhwala popanda kufunika kuyeretsa. Chifukwa magetsi amphamvu pawiri la mipope polypropylene imatengedwa odalirika.

ogwiritsa

Pamene ogwiritsa mankhwala, musati poyera chinyengo awo kapena kupinda monga polypropylene - ndi zinthu zovuta, kutanthauza kuti motsatana komanso zochita zina ziyenera kuchitika mwa zovekera polypropylene. Unsembe ntchito bwino kumanzere kwa akatswiri, mwinamwake pali chiopsezo chotenga osauka kwambiri Kutentha dongosolo. Ngati ndi kotheka, ndi polypropylene chitoliro zingakhale pang'ono wopindidwa, Kutentha kwa malo anakhumba ntchito yomanga choumitsira. Komabe, vuto la kuthamanga kwambiri mankhwala chuma akhoza kukumana ndi mapindikidwe kapena kuswa chomwecho.

Panopa opangidwa chubu kutalika mamita 4. Chopangidwa mankhwala a mitundu itatu, omwe lakonzedwa kwa makamaka ntchito (PN10, PN20, PN25). Kachitidwe Kutentha yakwera machubu polypropylene, Nthawi zambiri PN25. Other mtundu uwu khalidwe chakuti kumakula kwa mkati ndi aluminum zojambulazo Choncho, pulasitiki. Chifukwa chubu ikuthandizira wa gulu lachitatu angagwiritsidwe ntchito pa mavuto mpaka atmospheres 8 ndi kutentha 70 ° C, mmene nyengo - zaka 50. Koma ngati kuthamanga madzi ndi kutentha makhalidwe zingawonjezere moyo chubu adzakhala yafupika.

Pomaliza

mugule mipope polypropylene kwa Kutentha mu sitolo aliyense hardware. Mtengo wotsika, zimene zimapangitsa iwo alipo. mtengo zimadalira awiri (25 125 mm) ndi ranges kuchokera pafupifupi 40 1500 kapena zambiri pa rubles mita lalikulu. Ambiri kale mu mkulu khalidwe zakuthupi ndi mitengo demokalase.
